If possible, I would recommend visiting Loomis. It’s a bit of a Goldilocks school. Not too intense, but still rigorous. Nice size, so lots of clubs and programming. Good facilities and sports. Generally easy to get to. Rural feeling campus, yet walkable to shops and close to Hartford. Selective, but slightly less than some of its peers.
We aren’t a Loomis family, but know many who have enjoyed it, and think it is an excellent school to use as a comparative baseline.
